How much can more RAM make up for having a single core processor?
Let's say you bought one of those cheap laptops for $300-$400 that only comes with a single core AMD processor. Laptop comes with 2GB RAM but is expandable to 8GB RAM. If you maxed out the RAM would the laptop approach the speed of a dual core machine with 2GB RAM?
Or is the single core processor going to be just too much of a bottleneck?
There will be a point of diminishing returns on the RAM. Think about what RAM does, When you launch a program it loads up into RAM. As you access various parts of the program, it pulls them out of RAM instead of having to access the HD (which would slow you down). With enough RAM you can load a number of programs as you multitask.
With multi-core processors, the OS can assign different tasks to different processors, thus speeding things up. So if you're running a few programs at the same time, they will be processed faster.
BUT you have to think, who really runs more than one program at a time? Sure you can have a number of them launched and sitting in your task bar but who is actually spinning all those plates? Usually, as a human, you move from 1 task to another, So a multi-core processor is not really needed just to run multiple programs.
Where it really comes in handy is with complex-processor-intensive programs like video editing and gaming. Those programs have many tasks that happen at once so a multi-core processor pays off.
With a single core processor, running games and video editing apps is gonna be limited by the power of the processor. So you can load a program into RAM but that won't speed up the processing. However, you can imagine that there must be a sweet spot for every processor where the RAM can hold just enough stuff info to be processed at the processor's max speed. Therefore, at one point or another, you can have more stuff in RAM than can be processed.
In short, I guess, the processor is the bottleneck, depending on the types of programs you're running.
EDIT: Think of RAM as your shopping cart and the processor as the checkout lane. You are the OS and your job is to put the items on the belt at least as fast as the cashier can ring 'em up and bag 'em. The amount of groceries or the number of carts you use won't affect the speed of this process. If you could use more than 1 checout lane, then things would move faster of course.
